The Export JPG2000 command allows the user to export any loaded raster, vector, and elevation grid data sets to a JPG2000 format file. JPG2000 files are highly compressed and great for storing data such as satellite imagery. There is no size restriction on exported JPG2000 files, so you can store many terabytes worth of imagery within a single highly compressed JPG2000 file.
When selected, the command displays the JPG2000 Export Options dialog which allows the user to setup the export. The dialog consists of a General options panel which allows the user to set up the pixel spacing and target compression ration, a Tiling panel, and an Export Bounds panel which allows the user to set up the portion of the loaded data they wish to export. To generate a lossless JPG2000 format file, simply slide the Target Compression Ratio slider all the way to the left (1:1 target compression ratio).
Format Updates
| Version | Description |
|---|---|
| 26.2 | ERDAS ECW JP2 SDK update to v6.1 |
| 22.0 | Sped up tiled exports to ECW/JP2 files when multiple cores are available. [Item #GM-5063] |
| 20.1 | Changed default for JPEG2000 export option to use tiles to be disabled. Using tiles can result in visible tile edges at high target compression ratios.[Item #23857] |
| 19.1 | Made 'Skip Existing Tiles' option for tiled ECW and JPEG2000 export work when the export is run from different machines with the same target network folder. Now the separate machine exports should ensure that the same file isn't exported separately by each machine.[Item #23109] |
| 19.1 | Fixed bug causing some JP2 files to render invisibly (those with 1-bit alpha bands).[Item #24512] |
| 19.1 | Fixed save and reload of GMP file with JP2-compressed image layers to workspaces. The 'missing file' error will be gone after this fix and the image layers will load.[Item #24934] |
| 18.2 | Fixed flipped horizontally display of MrSID and JP2 files with a negative X spacing.[Item #22152] |
| 18.1 | Sped up export to ECW/JP2 formats targeting network folders. Now the export is done locally and copied to the network at the end. [Item #20635] |
